FFICEG FRANCIS JARVIS PATTEN, OF NEW YORK, N. Y.

ACETYLENE-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 623,559, dated April25, 1899.

Application filed April 16, 1898.

To (all whom, it may concern:

Be it known that I, FRANCIS JARVIS PAT- TEN, of the city of New York, inthe State of New York, have invented a new and useful Improvement inAcetylene-Gas Burners, of which the followingis a full, clear, and exactdescription, reference being had to the accompanying drawings, in whichFigure 1 represents a side elevation of the burner as it appears in use;and Fig. 2 represents a similar elevation, partly in section, thesectional part indicating the features of novelty I have introduced.

The chief difficulty with burners for acetylene gas appears to be toprovide a sufficient, supplyof air to the flame to prevent smoking,especially when the flame is turned low, and, second, to insure asufficiently complete combustion of the issuinggas at the point where itemerges from the Vent to prevent a deposit of soot or carbon at theopening of the vent, which clogs it up. The lines upon which it isgenerallyattempted to overcome these difficulties are to either supplyan air-blast to the flame or to mix air with the gas just before itissues from the vent, thereby furnishing the necessary oxygen requiredfor complete combustion, The plan I have adopted to produce the requiredflame is upon the first of these lines.

I am well aware that there is nothing essentially new about the generalform of burner shown having two impinging jets or flames directed fromthe burner at an angle of about forty-five degrees to the horizon ateach other and forming a single flat vertically-directed flame, thisbroad feature being common to many old types of burners. It is thearrangement of gas and air vents by which I obtain the desired resultthat constitutes the chief novelty of my invention, and this will beclearly understood by reference to the figures, in which like lettersdesignate the same parts.

In both figures, S is the stem of the burner.

B and B are forked ducts leading to the fine gas-vents G G, which arepreferably so inclined to each other in the same vertical plane that theissuing jets will proceed on lines at right angles to each other to apoint in the central vertical axis of the burner,

where they unite to form a single vertical flat flame in a plane atright angles to the plane of the two jets.

The gas tips or vents G G, Fig. 2, are surrounded by a cylindricaljacket formed by a continuation of the tubes B and B as far as the endsof the gas-vents G G, and at three or more points in the circumferenceof the jacket its walls are perforated or bored through, so that theholes comejust at the base of the gasvents G G. These little orificesare indicated in both figures as A A, and there may be any number ofthem, depending on the quantity of air required for the flame.

The effect and operation are as follows: On lighting the gas the twojets are atlame clear down to the tips of the vents G G. This heats thetips clear down to their bases inside their inclosing jackets. Theheated air thus formed in the jacket rises and in doing so draws afterit more cold air from the outside through the air-passages A A. Theescaping air from the jacket goes in the direction of the issuing jetinto the flame, thus supplying it with a sort of continuous air-blast,providing the necessary oxygen to secure complete combustion, and soprevent smoking or sooty deposits even when'the flame is turned low.

I am aware that devices closely resembling mine have been used. In somethe air is led into the gas tent or tip near the point of emergence andthere mixed with the gas before it comes out, and there are devices inwhich a blast is sent against the flame from the outside; but this isdone in a manner entirely different from that by which I insure a likeresultnan1ely, the bell-shaped cup or jacket surrounding the gas-ventand forming an air-heating chamber.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is the following:

1. A burner for acetylene gas consisting of a gas-vent upon which thegas is ignited, and a jacket surrounding said vent, said jacket havinginlets for the passage of air at or near its lower end, and an openingat the top for the delivery of the air to the ignited gas, substantiallyas described.

2. A burner for acetylene gas consisting of two gas-vents inclinedtoward each other and upon which the gas is ignited, and jacketssurrounding said vents, said jackets each having inlets for the passageof air at or near its lower end, and being open at the top for thedelivery of air to the'ignited gas, substantially as described.

In testimony whereof I subscribe my signature in presence of twowitnesses.
